Since the 1960s, metallic glasses (MGs) have attracted tremendous research interest in materials science and engineering, given their unique combination of mechanical properties. However, the industrial applications of MGs have been hindered due to their lack of ductility in bulk form at room temperature. In contrast, it was observed that MGs could exhibit excellent plasticity at the small size scale. In this article, we summarize the related experimental findings having been reported so far together with the possible origins of such a size effect in MGs. The enhanced plasticity of MGs in small volumes, together with their high mechanical strengths and remarkable thermoplastic formability, strongly implies that MGs are the promising materials for fabricating the next generation of micro- and nano-devices.
